Music Mode
The music mode is for use with any stereo music recordings, which
preserves the integrity of the stereo mix while augmenting it with a center
channel to anchor the image, and deriving enough surround content to
yield a spacious, three-dimensional listening experience. The Music
mode includes the control that allows the sound to be tailored to room
layout and personal preferences.
Cinema Mode
The Cinema mode is for use with stereo television shows and all programs
encoded in DTS Surround. The result is enhanced soundfield directionality
that approaches the quality of discrete 7.1-channel sound.
